... It also provides accurate and consistent current regulated outputs for a determined period of time before latch-off in the presence of overcurrent (OC) conditions. In addition the ISL6160 provides the enable signal to the on module DC-DC converter either upon module insertion to chassis or from a wake event request. See Figure 1 for typical application usage. ...

... VB(ulk) and +5V VA(ux) supplies providing soft start during hot insertion and overcurrent (OC) protection during operation. For VB control and protection, the ISL6160 features include an accurate current detecting comparator, current limiting for the range of both 25W and 50W capable power ports, a current regulated time delay to latch off and soft start turn-on ramp ...

... OR of both the VBx_En_L and the Local_Power_Enable being asserted. At that time the ISL6160 turns on the soft start mode protecting the primary supply rail from sudden in-rush current. During turn-on, the external gate capacitor of the N-Channel MOSFET (VB switch) is charged with current source resulting in a programmable ramp (soft start turn-on) ...
